This is an example project demonstrating how to configure and use the OAuth services provided by Google, i.e. how to enable 'Login with Google' functionality in Vaadin apps.
** NOTE **
To run this example, you will need to apply for an API key from Google and add it to the application.properties file under src/main/resources. Please follow this tutorial for instructions on how to do that, and more information about how this example works.
For local testing, you can add http://localhost:8080 to the URIs section and http://localhost:8080/login/oauth2/code/google to the Authorized URIs section in the Google API dashboard once you have created a key. You will still need an Authorized URL that is not localhost for the API Key to work; these are just for convenience.
Import the project to the IDE of your choosing as a Maven project.
Run the application using mvn spring-boot:run or by running the Application class directly from your IDE.
Open http://localhost:8080/ in your browser.
If you want to run the application locally in the production mode, run mvn spring-boot:run -Pproduction.
